Astragalusliuaiminii, a new species of Astragalus (Fabaceae) from Xinjiang, China.

A new species, Astragalusliuaiminii Z. Z. Yang & Q. R. Liu (Fabaceae), is described and illustrated from Xinjiang Province, China. The new species is close to A.wenquanensis S. B. Ho, but differs from the latter by leaves having a single leaflet (vs. 3-5 leaflets), and inflorescences with 1-2 flowers (vs. inflorescences with 5-7 flowers). It is also similar to A.monophyllus Maxim in leaf shape, but differs by its calyx expanding to become saccate and totally enveloping the pod (vs. calyx tubular, and ruptured by pod after flowering).

Clematismae (Ranunculaceae), a new species of C.sect.Meclatis from Xinjiang, China.

Clematismae Z.Z.Yang & L.Xie, a new species of Ranunculaceae from Xinjiang, China, is described and illustrated. The new species is morphologically similar to C.orientalis and C.glauca but can be distinguished for being a less hairy plant (hairy in C.orientalis), often 2-ternate leaves (1-2-pinnate for C.orientalis and C.glauca), lanceolate to linear-lanceolate leaflets (elliptic or ovate in C.glauca), larger flowers (smaller flower in C.orientalis) and narrowly lanceolate sepals with acute to slightly attenuate apex (narrowly oblong sepals in C.orientalis and ovate to broadly lanceolate sepals in C.glauca). The new species is endemic to the southern slope of North Tianshan Mountain in Central Xinjiang. The conservation status of the species is also discussed.
